I'm assuming the overlay works by GPS location of the copter, and camera feedback to say what direction it's pointed and the zoom level. Combine that with a topo map of the area and OpenStreetMaps, and it's straightfoward to map the camera output image to what part of the ground that represents, and generate the overlays.
